The 88-911-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, a type of anti-reflective coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 1.5mm at the edge and 8.7mm at the center, with an effective focal length (EFL) of 40.0mm. The radius of curvature for the first surface (R1) is 31.39mm, and the back focal length (BFL) is 35.13mm. The lens is made from n-SF11 Schott, a high-index glass with excellent transmittance and dispersion properties.
The YAG-BBAR coating on the lens reduces surface reflections, increasing the amount of light transmitted through the lens. This makes the lens ideal for applications where high transmission and low loss are critical, such as in imaging systems, beam delivery systems, and optical interconnects.
